South Korean polysilicon manufacturer OCI is planning to idle most of its production capacity. “We are closing all facilities in Gunsan except [production line] P1, which will be used only for manufacturing electronic-grade … poly-Si,” the company told pv magazine.
Financial news website Pulse and corporate magazine BusinessKorea had earlier reported OCI and polysilicon peer Hanwha Chemical were considering halting all domestic production lines because of the downward pressure on poly prices.
OCI told pv magazine its P1 factory accounts for 6,500 MT of its 52,000 MT annual polysilicon production capacity in South Korea. In terms of the company’s other domestic production lines, the manufacturer said: “For now, we do not have any plan to reopen it unless the price of solar grade poly-Si increases significantly.”
The company added, its 27,000 MT polysilicon facility in Malaysia will continue operations.
Hanwha Solutions told pv magazine simply: “We are examining the situation.”
Analyst Johannes Bernreuter said the closing of OCI’s Gunsan factory has not come out of the blue.
“The company had to fight an uphill battle not only against extremely low, subsidized electricity rates of $0.03/kWh and less for competitors in western China – [which] other, non-Chinese polysilicon manufacturers have to fight as well – but also against the rise of industrial electricity rates in South Korea to more than $0.10/kWh today – an increase of 71% since 2009, according to OCI,” Bernreuter told pv magazine.
The analyst said OCI’s basic chemical division, which includes the polysilicon business, has reported negative margins since the third quarter of 2018. “It is, hence, comprehensible that management wanted to get rid of this drag on profits,” he said. “What is less comprehensible is that OCI hardly compensates for the massive capacity loss of 52,000 MT in Gunsan with expanding its second polysilicon plant in Malaysia.”
According to Bernreuter, the Malaysian factory has enough space for expansion and enjoys an electricity rate close to that of western China. Previously stated expansion plans were intended to compensate any loss of South Korean capacity but OCI is now planning to increase polysilicon production in Malaysia by only a meager 10%.
Polysilicon specialist Bernreuter said the company’s investment strategy has been conservative since the first shake-out of the polysilicon industry, in 2011/2012. “Abandoning a sizable market volume of roughly 50,000 MT despite a competitive electricity rate in Malaysia – and no anti-dumping duties on imports from there into China – means hoisting the white flag of surrender against Chinese state capitalism,” said the analyst.
Bernreuter said Chinese competitor Tongwei recently revealed plans to increase its polysilicon production capacity from 80,000 MT to a staggering 220-290,000 MT in 2023. The company had already expanded capacity from 20,000 to 80,000 MT in 2018. “If you have ever had doubts about the ambition of the Chinese polysilicon industry, they should have been removed now,” he said.
In mid-January, China’s Ministry of Commerce announced anti-dumping duties applied to U.S. and South Korean polysilicon would remain for a further five years.
